Application filed October 18, 1907. Serial No. 897,985.

To all whom it may concern: I

Be it known that I, WILLIAM A. MOORE, citizen of the United'States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented certain new and useful Improvements in Oven-Doors; and .I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, ref erence being had to theaccompanying 'drawings,*and*"to the letters and figures of referencemarked thereon, which form a part of this specification.

This invention relates to new and useful improvements in oven doors forstoves and ranges, and comprises an oven door with a glass windowtherein through which the contents within the oven may be viewed withoutopening the oven door.

The present improvements relate to the oven door shown and describedin'Patent No. 687,251, granted to myself November 26, 1901, and consistsof means for protectingthe glass window in the oven door when said ovendoor is lowered and the baking pan or other utensil within the oven isWith drpwn from the oven onto the door, the oven door in such caseserving as a shelf, and the glass window being protected from breakagewhile the door is thus serving as a shelf.

The present improvements also relate to an outer closure or cover whichprotects the glass window from accidental breakage, and which may beeasily removed when it is desired to view the contents of the oventhrough the glass window.

The resent invention further relatesto means or uniting the window frameto the oven door, all of which will be hereinafter more fully'describedin connection with the accompanying drawings, of which- Figure 1, is afront elevation of an oven door with a glass window and having a portionof iny improvements applied thereto, the outer closure or cover for theglass window being detached. Fig. 2, is an enlarged vertical sectionthrough the center of the door as shown in Fig. 1 with the outer closureor cover in position. Fig. 3, is an elevation of the inner side of theoven door showing a glass window of elliptical form instead of circularform as in Fig. 1. Fig. 4, is a cross sectional view of one of thewindow bars.

In a detail description of the invention,

responding parts:

The oven door 1 is provided with the usual apertured lugs 2 which formhinges in the usual manner when united to the stove or range. In saiddoor there is provided an opening for the window, said opening beingeither of circular form or oval and surrounded by the circumferentialedge .3. Within this opening are arranged the outer and inner framemembers 4 and 5 of the window frame, which frame may likewise be ofcircular s uare"or oval form. These members have a utting flanges 6 and7 which enga e the respective frame members 4 and 5 an provide suitableannular spaces for packing rings 9 and 10. The outer packing rings 9 liebetween the inner circumferential sides of the frame members 4 and 5 andthe surrounding edge of the door 1, while the inner ackin rings 10 liebetween the inner clrcu erentia portions of said frame members 4 and 5and the glass window 11. To this extent the construction and manner ofuniting the glass Window to the oven door is substantially the same asthat shown and described in my former patent, and wherein the packingrings are provided as a means for preventing the glass window frombreaking under the jars and impacts due to the closing of the ovendoor.The outer and inner frame members 4 and 5 are united by means ofinwardly-extended pins 12 which project from-the inner side of the outermember 4 and extend through suitable openings 13 in the inner member 5.There are a suitable number of these pins 12, say for example, three, asshown in Fig. 1 or four as shown in Fig. 3. The inner ends of the'pins12 which lie beyond the inner side of the inner member '5 of the windowframe are provided with tasimilar reference characters indicatecorbetween said members 4 and 5 and the surinsi e of the glass window 11are a series of bars 15 which extend from one edge of the opening to theother edge and thus provide a support for a bake pan or other utensilinplacing the same in the oven or removing the same from the oven, theoven door 1 during such period being in its lowered or open po- 5sition. These protectin and su porting bars are cast integrally with t einner member 5 of the window frame. As shown in Fig. 4, thecross-sectional shape of the bars is wider at the base than at the innerside; this is a preferable form, for the reason that such bars may bemade of a minimum size 'in.'o'rder that the light may be unobstructedand 'at the same time saidbars may be of suitable strength tb supportthe utensils 15 placed thereon, and to protect the glass.

Owing to the tapering sides of the bars 15, the light entering the oventhrough the spaces between the bars is less obstructed t an would be thecase if the'bars were square or round in cross section. The outerclosure or cover 16 has an inwardly-turned annular rim which fits overan annular flange 17pro'ecting from the outer member 4 of the win owframe and surrounding the opening in said outer member. On the innerside of this cover 16 there is provided 7 a suitable number of springclamps 18 which engage the'inner side of the flange" 17 of the outermember 4 of the window frame and thus the cover 16 is held in positionto close scans the glass window in the oven door. A cen tral knob 19.isrovided on said cover by means of which 1tmay be removed by the hand.

Having described my invention, I claim:

An oven door having an opening therein, a frame for said openingconsisting of an inner member and an outer member, the latter memberbeing provided with an outwardly extended flange, the frame soconsisting of 40 two members, surrounding the opening in .said oven doorand being secured to said door by means'of pins extending from the outermember of said frame, a series ot bars extending from one side to theother side of the inner member of said frame and lying across theopening, a glass secured between the two members of said frame on theouter side of said bars, a detachable cover fitting over the outwardlyextended flange of the outer member of the frame, and s rin s on saidcover engagin the inner si e 0 said flange to maintain 1e cover inposition.

In testimony whereof I aifix my signature, in presence of two witnesses.
